Douglas, 30, was arrested last month after an undercover cop allegedly found half-a-pound of meth on Douglas at the swanky Hotel Gansevoort, law enforcement officials said.

Cameron is accused of running a well-oiled drug operation, selling hefty amounts of methamphetamine between New York and Los Angeles, delivering the addictive substance in person, or via Fed Ex from a California hotel, according to the criminal complaint.

One source said that Sott herself looked tired and worn. A criminal complaint against Sott said that inside the battery compartment of the toothbrush she brought her boyfriend, guards found "about 19 glassines" with a brownish substance "that appeared to be heroin."

Field test indicated it was, in fact, about seven grams of heroin.

Law enforcement sources said Sott was at a relative's Manhattan apartment when Cameron Douglas called and asked her to bring down items to him Investigators took Sott back to the Gansevoort Hotel, where she had a room, and there they discovered more drug paraphenalia, sources said.

When DEA agents arrested Sott, she said "that she was not aware of the contents of the toothbrush that she delivered," the complaint said.
